Sputtering (or PVD) is the newest cutting edge for product colouring and consists in the physical deposition of vapour (Physical Vapour Deposition), i.e. the coloured film layer and the substrate of the material to be coloured are sealed together at molecular level, vacuum and very low temperatures.
The process occurs under completely dry conditions and the sealing yields a harder and more compact surface, with a low friction factor; it becomes more anti-corrosive, scratch-resistant and anti-printing, and has a higher transparency.
Unlike the old and highly pollutant galvanic electro deposition of colour, the sputtering process distinguishes itself by its several advantages, such as its non-toxicity for humans, its resistance, tidiness, lightness, eco-friendliness and its inexpensive costs.
Furthermore, with the sputtering technique, we can colour any kind of material, ranging from metal (chromium, aluminium, copper, brass…) to ceramics and even plastic.
Centro laser can create any kind of colouring and offer unique and highly innovative technical processes thanks to a close cooperation with its customers.
However, in order to understand the innovative strength of the sputtering technique, you must discard the old colour galvanic electro deposition, which is highly pollutant for the environment and toxic for humans.
Indeed, sputtering represents the newest cutting edge for product colouring that will completely change the colouring process, offering an historic turning point full of great advantages.
Resistance, cleanliness, lightness, eco-friendliness and inexpensive costs. These are its incredible advantages. PVD is also known as “Physical Vapour Deposition”.
A physical and not just a chemical process
Concerning all aspects, sputtering is the best technology available for the colouring of your product. The reason for this is that the coloured film layer and the substrate of the material to be coloured are sealed together at molecular level in vacuum conditions.
What does it mean?
That with this technique, we can colour whatever kind of material; from metal – chromium, aluminium, copper, brass – to ceramics and even plastic.
The latter has always presented a challenge for any older technique before sputtering came onto the scene, since we all know that plastic does not often withstand the high temperatures reached with the older colouring techniques. However, from now on, even the most temperature-responsive materials can be coloured using the physical deposition of vapour – the «Physical Vapour Deposition» technique – the «Physical Vapour Deposition» – known as sputtering. In other words, this technique annuls the unpleasant melting of plastic materials.
Cleanliness, inexpensive costs and respect for the environment.
Sputtering is the cleanest colouring technique currently available on the market.
The process occurs under completely dry conditions, and the physical sealing between the colouring and the material to be coloured yield a harder and more compact surface, with low a friction factor; it becomes more anti-corrosive, scratch-resistant, anti-printing and has better transparency features, which were inconceivable up until now. And there’s more…
Thanks to the above-mentioned features, the sputtering technique will colour your product in an incredibly efficient way.
Along with obtaining the world’s most uniform and thinnest coating, you will also save money considerably: no further colouring processes needed, no further colouring material required. Hence there will be no more waste and an incredible decrease in cost, while obtaining top-quality and incomparable results.
Furthermore, the flagship of this new technique is its biocompatibility. Pollution towards both the environment and human health has become outdated thanks to the galvanic electro deposition of sputtering.
Thanks to their slimness and resistance, thin coatings in every colour can be combined to several layers with almost endless combinations.
